Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus for producing a grey-tone image having areas of different average density values which are given by an n-digit binary number, all the bits of the binary number being interrogated in parallel by clock patterns.  For the area to be printed an elemental area containing 2n pulses is selected which is printed in a total cycle or 2n-1 clock pulses or the clock pattern.  In this total cycle, at each clock pulse the drive of each pair of dots is determined in a manner such that the most-significant bit of the binary number is always used for driving while the remaining bits are used a number of times which depends upon their positional values.  For this purpose, for each position of the binary number the clock pattern has a number of clock pulses which corresponds to the value of this position.  The clock pulses for the individual positions are non-uniformly distributed in time, however, no clock pulses for the second and any further positions of the binary number coincide in time.  Before each new print line the pattern will if required be shifted by additional clock pulses.

Abstract: ABSTRACT OF THE DISCLOSURE    The disclosed invention relates to a solar energy collector in a conversion system.  The collector is made from common glass tubing lengths of different diameters and comprises a first outer clear glass cylindrical tube having approximately a semi-cylinder surface portion mirror coated for reflection and a collector tube inside the first tube having an energy absorbing coating on its exterior surface,  The tubes resemble over-sized test tubes in that one end is closed.  The collector is held in place inside the outer tube by a spacer-support element snapped on the closed end of the collector.  The open end of the outer tube is sealed to the wall of the collector, and the space is evacuated.  An open-ended fluid handling tube of glass is inserted into the collec-tor tube and has a spiral or helical baffle along its length to guide working fluid issuing into the collector near its closed end along the wall thereof and absorb collected heat.  Several of the energy collectors are detachably connected into a manifold for circulation of working fluid (air or water or the like) into the hand-ling tube and receive working fluid flowing from the collector tube.  The manifold provides for collector tubes to depend on opposite sides as a module covering predeter-mined area of rooftop or like solar exposure.  The working fluid carrying the energy is utilized in a heating or cool-ing system.

Abstract: ABSTRACT OF THE DISCLOSURE         Steam flow to a turbine is reduced by partially closing intercept control valves to reduce turbine speed to a reference speed after sudden increases above this speed caused by sudden decreases in turbine load.  Circuit-ry for developing a command signal for closing the valves in response to a difference between the reference speed and the actual speed of the turbine is provided.  The command signal magnitude is varied to cause rapid closing motion of the valves during that portion of valve movement having little effect on steam flow and less rapid closing motion during that portion of valve movement having substantial effect on steam flow, thereby compensating for a nonlinear relationship between valve movement and change in steam flow.

Abstract: NOISE ATTENUATING ENGINE ENCLOSURE    ABSTRACT           The internal combustion engine of a tractor is housed within an engine enclosure comprising a top panel and a pair of side panels.  Each side panel is provided with a plurality of perforated areas to permit engine cooling air to flow between the inside and -the outside of the enclosure.  A secondary panel is pro-vided for each perforated area and is disposed inside the enclo-sure in spaced relationship from its associated wall panel.          Each secondary panel is in registry with its associated per-forated area but is larger in area than its associated perfor-ated area, so that the edges of the secondary panel extend beyond the edges of the perforated area.  This arrangement permits air to pass in or out of the enclosure in a path other than a straight line and serves to attenuate engine noise originating in the enclosure by preventing sound waves from passing in a direct path from the engine through the perfor-ated areas to the outside of the enclosure.  One or more per-forated areas are provided in a fixed portion of the side panel as well as in a movable (hinged) portion of the side panel which opens to afford access to the interior of the engine enclosure.

Abstract: ABSTRACT OF THE DISCLOSURE           A transmission system in which wide band electrical signals are transmitted along a transmission line has repeater stations located at intervals along the line for boosting and equalising the signals.  Each repeater station has an equaliser in which a series resonant circuit is connected in parallel with two transverse resistive members of a resistor T pad and a parallel resonant circuit connected in series with a leg member of the T pad, the two resonant circuits being timed at substantially the same frequency.  The equaliser has a frequency response characteristic which generally complements that of the section of the transmission line which it covers and is capable of adjustment to match the section of transmission line which feeds it.  The adjustment required will vary with the length of the section of transmission line and temperature changes.  The repeater station incorporates automatic control means which sense a pilot signal transmitted along the section of trans-mission line and responds to the monitored level of the pilot signal to automatically adjust the characteristic of the equaliser.

Abstract: ABSTRACT OF THE DISCLOSURE:                Presence of metals such as copper and nickel being economically interesting metals are determined as to existence thereof in the content of manganese nodules according to a method by means of analysis of the activa-tion gamma spectrum of manganese nodule samples after a neutron irradiation thereon. The sample is irradiated with fast neutrons and from the resulting gamma spectrum the ratio of radiation intensities of two main component parts preferably manganese and iron is taken in order to de-termine the percentage metal content by way of empirically obtained geochemical correlation-data which reproduce the percentage parts of further elements dependent upon pre-pertional ratio of two main elements of the manganese nodules.
